What causes thumb pain?
You may be wondering why your thumb hurts. This study says there are several main reasons for pain around the thumb. Let us look at each one.
What is thumb arthritis at the base?
One common cause is called thumb carpometacarpal osteoarthritis. That is a long word. Doctors also call it rhizarthrosis. This arthritis happens where your thumb meets your wrist. The bones rub together because the cushion between them wears away. This rubbing causes pain and swelling.
Research shows that this kind of arthritis is very common. It makes it hard to pinch or grip things. You might feel pain when you open a jar or turn a key.
What are swollen thumb tendons?
Another cause is called de Quervain’s stenosing tenosynovitis. That sounds complicated. It means the tendons on the thumb side of your wrist get swollen and irritated. Tendons are like strong cords that help your thumb move.
When these tendons swell, they do not slide smoothly. This causes pain when you move your thumb or wrist. You might feel pain when you make a fist or hold your baby.
What about nerve problems in the wrist?
The study also talks about carpal tunnel syndrome. This happens when a nerve that runs through your wrist gets squeezed. This nerve helps you feel things in your thumb, pointer finger, and middle finger.
When the nerve is pinched, you might feel tingling, numbness, or pain. Sometimes this pain reaches into the thumb area. It can wake you up at night.
What is nerve pinching near the thumb?
There is another nerve problem called Wartenberg’s syndrome. This happens when a different nerve near the back of your wrist gets pinched. This nerve helps you feel the back of your thumb.
When it is squeezed, you might feel pain, tingling, or strange feelings on the thumb side of your hand. It can happen if you wear tight watches or bracelets.
All these problems can cause pain in the same area. That is why it is important to find out which one is causing your pain.
How Do Doctors Find Out What Is Wrong?
According to this study, doctors use several steps to figure out what is causing your thumb pain.
What questions will the doctor ask?
First, the doctor will ask many questions. They want to know when the pain started. They will ask what makes it better or worse. They want to know if you do any work or hobbies that use your hands a lot.
This detailed medical history helps the doctor understand your pain better. Every detail matters.
What tests will the doctor do on your hand and thumb?
Next, the doctor will do a physical examination. This means they will gently touch and move your thumb and wrist. They will look for swelling. They will press on certain spots to see if it hurts.
They might ask you to do certain movements. These targeted tests help the doctor see which part is causing the problem.
Should the doctor take pictures inside your hand?
Sometimes, the doctor needs to see inside your hand. Medical evidence supports the use of modern imaging techniques. These are special pictures that show bones, tendons, and nerves.
X-rays show the bones. They can show if there is arthritis. Ultrasound uses sound waves to show tendons and soft parts. MRI scans give very detailed pictures of everything inside.
These pictures help the doctor be sure about what is wrong.
What can be done to help thumb pain?
Studies indicate that there are many ways to help thumb pain. The right treatment depends on what is causing the pain and how bad it is.
What simple things can you do?
Research shows that conservative measures can help many people. Conservative means treatments that do not involve surgery. These include:
- Resting your thumb and avoiding movements that hurt.
- Wearing a splint or brace to keep your thumb still.
- Taking medicine to reduce pain and swelling.
- Doing gentle exercises to keep your hand moving.
- Applying ice or heat to the sore area.
Many people feel better with these simple steps. They are often the first things to try.
When might surgery help?
According to this study, if the pain is very bad and does not get better with conservative treatment, surgery might be needed. Surgical interventions are operations done by a doctor.
The type of surgery depends on the problem. For thumb arthritis, doctors can remove damaged bone or rebuild the joint. For swollen tendons, they can make more room for the tendon to move. For pinched nerves, they can release the pressure.
Surgery is usually only done when other treatments have not worked. Your doctor will talk with you about whether surgery is right for you.
